Description

Technical Field

[0001] This utility model relates to a limiting mechanism and its slide rail assembly, wherein the limiting mechanism can limit the position between slide rails. Background Technology

[0002] With the mature development of the computer industry and cloud technology, the demand for electronic data access is increasing, especially in artificial intelligence (AI), such as ChatGPT. To meet the massive information access demands, the current server equipment structure consists of multiple server chassis within a server rack. The server chassis and the server rack are connected by a sliding rail structure. For example, each side of the server chassis has a first sliding rail, and each side of the server rack has a second sliding rail relative to the first sliding rail, allowing the first sliding rail to move on the second sliding rail. Summary of the Invention

[0003] The main objective of this utility model is to provide a limiting mechanism and its slide rail assembly, wherein the limiting mechanism uses an operating component to cooperate with a limiting stop component, thereby improving the effectiveness of switching the state of the limiting stop component.

[0004] Another objective of this utility model is to provide a limiting mechanism and its slide rail assembly, wherein the limiting stop of the limiting mechanism cooperates with the limiting part of the slide rail to improve the effect of limiting distance with a shorter stroke.

[0005] Another objective of this utility model is to provide a limiting mechanism and its slide rail assembly, which, when the travel distance of the limiting distance is completed, forms an installation distance between the rear of the slide rail and the installation module, thereby improving the efficiency of installation without obstruction for the operator.

[0006] Another objective of this utility model is to provide a limiting mechanism and its slide rail assembly, wherein the operating component is pulled out or pushed back to the slide rail in a kit manner, thereby improving the efficiency of operation for the operator.

[0007] To achieve the above objectives, the present invention employs a limiting mechanism comprising: an operating member having a space to form a backing portion; and a limiting stop having a stop portion and a stop body higher than the stop portion, wherein when the operating member is in a first operating state relative to the limiting stop, the stop portion is against the backing portion and the stop body is located in the space, or when the operating member is in a second operating state, the stop portion is not against the backing portion and the stop body is against the backing portion.

[0008] To achieve the above objectives, the present invention employs a slide rail assembly comprising: a first rail having a limiting portion; a second rail that is movable relative to the first rail; a third rail that is movable relative to the second rail; and a limiting mechanism having a limiting stop attached to the third rail, wherein a limiting distance is set between the limiting stop and the limiting portion, and when the second rail moves toward the first rail to complete the travel of the limiting distance, the limiting stop is fixed at the limiting portion.

[0009] To achieve the above objectives, the present invention employs a slide rail assembly comprising: a first rail; a second rail, the second rail being movable relative to the first rail; a third rail, the third rail being movable relative to the second rail; a reinforcing rail disposed on the first rail and having a limiting portion; and a limiting mechanism having a limiting stop attached to the third rail, wherein a limiting distance is set between the limiting stop and the limiting portion, and when the second rail moves toward the first rail to complete the travel of the limiting distance, the limiting stop is fixed at the limiting portion.

[0010] Based on the aforementioned features, when the travel distance of the limiting distance is completed, an installation distance is formed between the rear of the second rail and the rear of the third rail and an installation module.

[0011] Based on the aforementioned features, the limiting mechanism includes an operating member, which has a space to form a resting portion, and the limiting stop has a stop portion and a stop body higher than the stop portion. When the operating member is in a first operating state relative to the limiting stop, the stop portion rests against the resting portion and the stop body is located in the space; or when the operating member is in a second operating state, the stop portion does not rest against the resting portion and the stop body rests against the resting portion.

[0012] Based on the aforementioned features, the limiting stop has a limiting hole, and the limiting part is a stop point, and the limiting hole is relative to the stop point.

[0013] Based on the aforementioned features, the limiting stop is provided with a limiting hole, which is relative to the limiting portion, and the stop body is a first arched piece and a second arched piece, with the limiting hole located between the first arched piece and the second arched piece.

[0014] Based on the aforementioned features, the operating member has a groove communicating with the space, and the operating member uses the groove to enclose the front section of the third rail.

[0015] Based on the aforementioned features, the groove has a limiting surface, which is relative to the front end surface of the third rail, and the rear end surface of the operating member is relative to the front end surface of the second rail. When the operating member performs a first operating state, the front end surface of the third rail approaches the limiting surface and the rear end surface of the operating member approaches the front end surface of the second rail. Or when the operating member performs a second operating state, the front end surface of the third rail moves away from the limiting surface and the rear end surface of the operating member moves away from the front end surface of the second rail.

[0016] Based on the aforementioned features, it may further include a carrier whose side is connected to the third rail. When the travel of the limiting distance is completed, an installation distance is formed between the rear of the second rail, the rear of the third rail, and the rear of the carrier and an installation module.

[0017] With the aforementioned technical means, the limiting mechanism, in conjunction with the operating component and the limiting stop, effectively switches the state of the limiting stop. The limiting stop, in conjunction with the limiting part, achieves a shorter travel distance. When the travel distance is completed, the installation distance is formed, allowing the operator to install without obstruction. Furthermore, the operating component is pulled out or pushed back in a kit-like manner, facilitating the operator's use. The aforementioned effects complement each other. Attached Figure Description

[0092] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0093] Example

[0094] Please refer to the following first. Figures 1 to 19 As shown, this utility model is a limiting mechanism 10, comprising: an operating member 11, which has a space 111 to form a backing portion 112; and a limiting stop 12, which has a stop portion 121 and a stop body 122 higher than the stop portion 121. When the operating member 11 is in a first operating state S1 relative to the limiting stop 12, the stop portion 121 rests against the backing portion 112 and the stop body 122 in the space 111, so that, Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, when the limiting mechanism 10 is not activated, the stop 122 is housed in the space 111; or when the operating member 11 performs the second operation state S2, the stop 121 does not rest against the abutment 112 and the stop 122 rests against the abutment 112. Thus, as... Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, when the limiting mechanism 10 is activated, the stop 122 moves to the abutment part 112.

[0095] To further explain, the limiting mechanism 10 is integrated into the slide rail, such as... Figure 11 , Figure 12 , Figure 13 , Figure 14 As shown, the slide rail assembly 20 of the first embodiment includes: a first rail 21 as an outer frame, the first rail 21 having a limiting portion A; a second rail 22 as a middle frame, the second rail 22 being movable relative to the first rail 21; and a third rail 23 as an inner frame, the third rail 23 being movable relative to the second rail 22, and a limiting stop 12 being attached to the third rail 23, with a limiting distance D1 set between the limiting stop 12 and the limiting portion A, the limiting distance D1 being preferably 5cm. When the second rail 22 moves toward the first rail 21 to complete the stroke of the limiting distance D1, the limiting stop 12 is fixed at the limiting portion A. Thus, when the stroke of the limiting distance D1 is completed, there is an installation distance D2 between the rear of the second rail 22 and the rear of the third rail 23.

[0096] Continuing from the above, the limiting stop 12 is provided with a limiting hole 123. The limiting hole 123 is relative to the limiting part A, and the stop body 122 is a first arch piece B1 and a second arch piece B2. The limiting hole 123 is located between the first arch piece B1 and the second arch piece B2. The limiting hole 123 is fastened to the limiting part A, or the limiting part A can be a stop point, and the limiting hole 123 is relative to the stop point.

[0097] Continuing from the above, the limiting stop 12 has a fixing portion 124 and a spring portion 125. The spring portion 125 is located between the fixing portion 124 and the stop portion 121, with the spring portion 125 relative to the space 111. The spring portion 125 has a first segment C1 and a second segment C2 extending from the first segment C1. The first segment C1 is a flat segment and the second segment C2 is an inclined segment. The first segment C1 extends from one end of the fixing portion 124, and the second segment extends from one end of the stop portion 121 and extends a hook portion 126 from the other end of the stop portion 121. In addition, the fixing portion 124 is provided with a fixing hole M, and the third rail 23 is provided with a first fixing hole M1, through which a fixing member 127 passes to the first fixing hole M1.

[0098] To further explain, the abutting part 112 has an inclined surface E1, an abutting surface E2 extending from the inclined surface E1, and a concave surface E3 extending from the abutting surface E2. The first arch piece B1 and the second arch piece B2 extend from the inclined surface E1 to the abutting surface E2 or from the abutting surface E2 to the inclined surface E1, and cooperate with the hook part 126 relative to the concave surface E3.

[0099] To further explain, the operating member 11 is provided with a groove 113 communicating with the space 111, and the operating member 11 uses the groove 113 to fit the front section L of the third rail 23. The groove 113 has a limiting surface F, which is relative to the front end surface 231 of the third rail 23, and the rear end surface 114 of the operating member 11 is relative to the front end surface 221 of the second rail 22. When the operating member 11 performs the first operating state S1, the front end surface 231 of the third rail 23 approaches the limiting surface F and the rear end surface 114 of the operating member 11 approaches the front end surface 221 of the second rail 22. Or when the operating member 11 performs the second operating state S2, the front end surface 231 of the third rail 23 moves away from the limiting surface F and the rear end surface 114 of the operating member 11 moves away from the front end surface 221 of the second rail 22.

[0100] Further explanation: The operating member 11 has a first limiting portion 115, which is disposed on the abutting portion 112. A first limiting surface F1 is formed on the outer side of the abutting portion 112. The front end of the first limiting portion 115 has a first limiting groove G1, and the rear end of the first limiting portion 115 has a limiting body H. The operating member 11 also has a second limiting portion 116, which has a second limiting groove G2 and a second limiting surface F2 formed on the outer side of the second limiting groove G2. Therefore, the first limiting surface F1 and the... The second limiting surface F2, and the third rail 23 has a first wall 232, a second wall 233, and a third wall 234 connecting the first wall 232 and the second wall 233. Each of the first limiting surfaces F1 and each of the second limiting surfaces F2 can limit the first wall 232 and the second wall 233, and the first limiting part 115 and the second limiting part 116 limit the third wall 234. At the same time, the fixing part 124 is opposite to the second limiting groove G2, and a third limiting surface F3 is formed on the inner side of the abutment part 112. Each of the third limiting surfaces F3 limits the two sides of the fixing part 124. In addition, the limiting body H is provided with an elongated hole H1 and the third rail 23 is provided with a second fixing hole M2. A limiting member 117 passes through the elongated hole H1 to the second fixing hole M2, so that the operating member 11 can be limited to be pulled out or pushed back.

[0101] To further explain, the first rail 21 forms a receiving groove 211, which is a recessed feature. When the second rail 22 does not move toward the first rail 21, the limiting stop 12 stops in the receiving groove 211, or when the second rail 22 moves toward the first rail 21, the limiting stop 12 leaves the receiving groove 211.

[0102] like Figure 15 As shown, it may further include a carrier 40, the side of which is connected to the third rail 23. When the travel of the limiting distance D1 is completed, the rear of the second rail 22, the rear of the third rail 23, and the rear of the carrier 40 form the installation distance D2 with the mounting module 30. A first connector may be mounted on the carrier 40, and a second connector may be mounted on the mounting module 30, so that the installation distance D2 facilitates the engagement of the first connector and the second connector.

[0103] like Figure 16 , Figure 17 , Figure 18 , Figure 19 As shown, the slide rail assembly 20A of the second embodiment includes a reinforcing rail 24, which is disposed on the first rail 21. The limiting portion A is disposed on the reinforcing rail 24, and the receiving groove 211 is open. The slide rail assembly 20A of the second embodiment differs from the slide rail assembly 20 of the first embodiment only slightly in structure, which will not be described in detail. Therefore, both the slide rail assembly 20 of the first embodiment and the slide rail assembly 20A of the second embodiment have the same function, such as activating the... The limiting mechanism 10 first pulls the operating member 11 axially out and pushes the limiting stop 12 to the limiting height, which is also close to the height of the limiting part A. When the carrier 40 is pulled out, the limiting hole 123 will enter the limiting part A, thus forming a limiting stop and holding the carrier 40 here. Or, if it is necessary to release the limiting mechanism 10, the operating member 11 can be pushed back in the forward direction, and the limiting hole 123 will automatically retract to the lower position and disengage from the limiting stop 12, thus releasing the limiting function.
